Hello,
This is driving me crazy, I'm never installed software via a GPO before and have been asked to install an MSI silently to our users.
MSI - https://www.citrix.com/downloads/citrix-receiver/additional-client-software/hdx-realtime-media-engine-201.html
Some already have an older version of the MSI some don't have it.
I've copied the file to a share that all users can get to and tried to assign a package to my Computer or User policy and neither works.
I've followed this.

In the event logs all I see is event code 1040 which says "Beginning a Windows Installer transaction....."
